According to a news report at U. Penn, the Martin and Margy Meyerson Chair of Urbanism and professor and chair of landscape architecture at the Stuart Weitzman School of Design, Richard Weller, identified "hotspot cities," which are places where human settlements are threatening the already declining existence of biodiversity.
In June, Weller hosted a two-day convention at Perry World House, known as the Hotspot Cities Symposium. Various leaders from around the globe came to the symposium to present "scientific research, environmental studies, policy questions and political problems" to discuss ways of protecting and connecting current habitats. Such attendees included landscape architects, architects, scientists, scholars and government officials.
The symposium was held leading up to the Design With Nature conference influenced by Professor Ian L. McHarg's book that presented an approach to the planning and design of communities, entitled Design With Nature.
